The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing:
Cyclone gas-liquid separator described in the present invention, its structure as shown in Figure 1, main body is the cylindrical chorista 9 of a hollow, is fixed with obturator and a following obturator on one respectively at the upper/lower terminal of described chorista 9.Wherein, described go up obturator by upper end cover 10, embed the back taper 5 at upper end cover 10 centers and open and constitute in the overflow pipe 7 at back taper 5 centers, described obturator down is made of the inner cone 3 at bottom end cover 11 and embedding bottom end cover 11 centers, after the airtight connection of said modules, forms a disengagement chamber 2.In addition, on described chorista 9 upper end sidewalls, have the both direction inlet tube 1 relative, parallel to each other that is tangential access with the chorista excircle, on described chorista 9 lower end sidewalls, have the outlet 4 that is tangential access with the chorista excircle, wherein, the direction of described outlet 4 is identical with the inner eddy flow direction of being determined by two inlet tubes 1.
The separation principle of this New-type Swirl Flow gas-liquid separator also utilizes two kinds not dissolve each other the density of medium difference and carry out centrifugation.After liquid two inlet tubes relative by direction with the blending agent of gas enter separator, under the effect of pressure, produce rotation at a high speed in device interior, form the eddy current of rotation at a high speed.Drive in the mixed liquor process descending along separator at eddy current, under centrifugal action, density is than heavy phase---and liquid is got rid of to wall; Simultaneously, gently phase---gas is pushed to the center to density.In this process, because this kind cyclone gas-liquid separator center fixation has an inner cone 3, separate out after making the gas that highly disperses in mixed liquor and inner cone 3 contacting, make near the enrichment region that becomes gas the inner cone, and the gas of separating out enters overflow pipe 7 by overflow pipe inlet 8 and discharges through overflow pipe outlet 6 along upwards migration of inner cone.Here, the main purpose that adds inner cone is: one, for the condition of being beneficial to that provides of separating out of gas, increase the probability that gas is separated out.Two, reduced the radially migration distance of gas, isolated gas is discharged fast to the center.
In addition, be installed on the back taper 5 at separator top in the present invention, can make the gas that accumulates in the separator top under the carrying of the mixed liquor that enters, migrate downwards in inclined-plane along inwall, and discharge by overfall, avoid near upper end cover, retaining all the time the gas that can not discharge, thereby improve separative efficiency.
